4 Claims.

This invention relates to a traveler device, and it is an object of theinvention to provide a device of this kind adapted to be mounted forrotation above and independently of a bobbin spindle of a ring twisterand which device provides an effective means to stretch the yarn whileit is being twisted.

Another object of the invention is to provide a device of this kindincluding a fan which, when in operation, will broadcast a draft of airto provide an elfective medium to blow off from the adjacent portions ofthe twister all lint and other articles which would otherwise settlethereon and also to keep slugs from twisting in the yarn.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of our improvedtraveler device whereby certain important advantages are attained andthe device rendered simpler, less expensive and otherwise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of our invention will hereinafter be definitelyclaimed.

In order that our invention may be the better understood, we will nowproceed to describe the same with reference to the accompanying drawing,wherein- Figure 1 is a fragmentary view partly in section and partly inelevation illustrating a traveler device constructed in accordance withan embodiment of our invention;

Figure 2 is a view in top plan of the fan carrying member;

Figure 3 is a view in elevation of the threading key.

As disclosed in the accompanying drawing, l denotes a plate foradjustable connection by the guide lid lappet of a twister frame andwhich plate is provided at its outer end with a bearing head 2 for theupper end portion of a tubular spindle 3. The mounting for the upper endof this spindle 3 is such as to permit the same to readily rotate with aminimum of frictional resistance.

This spindle 3 when in working position is directly above the spindle 4upon which the bobbin 5 is mounted. As is well known, this spindle ttogether with the applied bobbin 5 passes axially through a travelerring 5 carried by the ring rail 1 and which rail is caused to rise upand down at a predetermined speed with respect to the spindle 4 or moreparticularly the bobbin 5. The mechanism for effecting this movement ofthe ring rail 7 forms no part of the present invention.

Coacting with the ring 6, as is well known, is

. the traveler 8 through which is passed the yarn thread 9 which leadsfrom the conventional degated bolt l2 which threads into the lower end1| of the spindle 3 whereby the member H is efiectively clamped to thelower end portion of the spindle 3 for rotation therewith. An endportion of the member H is provided with a guide eye 12 through whichthe yarn thread 9 is freely directed. As is clearly illustrated in theaccompanying drawing, the yarn thread 9 as it leaves the delivery rollsis threaded from above down onto the spindle 3 and out through one ofthe side openings Ill through the eye l2 and from a there through thetraveler ring to the bobbin. This threading of the yarn 9 assures aneffective stretch to the yarn and there will be a different tensionorpull on the yarn when the thread is directed through the different open-0 ings !0 in the spindle 3. I

The member H at the opposite ends thereof and at opposite. sides isprovided with the fan blades B extending above and below the member l I.These blades 13 are of such size and form 35 to create an effective airblast as the member ll rotates under the action of the yarn to blow offfrom adjacent portions of the twister all lint and other particles whichwould otherwise settle thereon and also to keep slugs from twisting into40 the yarn. These fan blades B also provide resistance to the member Hin its rotation to further impose stretch upon the yarn.

In initially threading the yarn thread 9 a key A is preferably used.

From the foregoing description it is thought to be obvious that atraveler device constructed in accordance with our invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that our invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason we do not wish to be understood as limitingourselves to the precise arrangement and formation of the several partsherein shown in carrying out our invention in practice except ashereinafter claimed.

We claim:

1. In combination with a bobbin spindle and traveler of a ring twister,a tubular spindle, means for rotatably supporting said tubular spindledirectly above the bobbin spindle, said second spindle being open at itstop and having an opening in its side wall, an elongated member carriedby the lower end portion of the second spindle and having a thread guideat an end portion thereof, the thread from the delivery rolls of thetwister extending down from above through the second spindle out throughthe opening in the side wall of the second spindle and through thethread guide of the member to the traveler associated with the bobbinspindle, and a fan blade carried by each end portion of the member, thefan blade at one end portion being at one side of the member and theother fan blade being at the opposite side of the member.

2. In combination with a bobbin spindle and traveler of a ring twister,a tubular spindle, means for rotatably supporting said tubular spindledirectly above the bobbin spindle, said second spindle being open at itstop and having an opening in its side wall, an elongated member carriedby the lower end portion of the second spindle and having a thread guideat an end portion thereof, the thread from the delivery rolls of thetwister extending down from above through the second spindle out throughthe opening in the side Wall of the second spindle and through thethread guide of the member to the traveler associated with the bobbinspindle, and fan blades carried by the member.

3. In combination with the bobbin spindle and traveler of a ringtwister, a tubular spindle open at its top, means for rotatablysupporting said second spindle above the bobbin spindle, said secondspindle in its side wall being provided with a series of longitudinallyspaced openings, an elongated member carried by the lower end portion ofthe second spindle and having a thread guide adjacent to an end thereof,and fan blades carried by the member at spaced points lengthwisethereof.

4. A thread tension device for a ring twister comprising a tubularspindle, means for supporting said spindle above a bobbin spindle, theupper end of the first spindle being open, the side wall ofthe firstspindle having an opening, a member carried by the lower portion of thefirst spindle and having a thread guide and fan blades carried by theextremities of the member, one blade extending along a side of themember and across the adjacent end of the member, the second fan bladeextending along the opposite side of the member and across the adjacentend thereof.
